My proposed plan to improve gameplay and change the style of warfare would be to either make upgrade levels for the supply: (I, II, III)
1. Medipacks, Grenade Launchers, Tactical Shields
2. Light Armor, Rocket Launchers
3. Armor, RPG Launchers
Another idea would be to simply change the weapon(s) given by the Super Supply into something more balanced. (Perhaps a RPG for a Rocket Launcher? )
